This all started because it was 94F outside, and I needed to block the heat from the rest of the house from getting into my AC-cooled room. I looked up the price of a curtain rod and went about installing curtains the old way.

• Curtain Rod: $9
• Curtain: $40 (need to be thick to absorb the heat so tends to be more expensive)

That was $49, and for me, with my 3D printer, that is entirely too expensive. So I grabbed my $12 filament and got to designing. I tried this as my first creation because I wanted the path of least resistance.

The first thing I needed to design was a rod that would hold decently, be fast to print, and not require a lot of filament. I came up with this design:

The rod was essentially as I needed for it to be daisy-chained with other rods but be fast to print. The rod needed to be held up so I made a holder:

Now that I completed that, I just needed 2 more items. The first would be an insert in the fabric like you see in shoes:

This would be made of 2 parts: a female backend that's rather thick and a male front end that is designed to be more presentable and thin. The other item would be a simple hook for the hole to be held onto by the rod.

With these combined, I have made a complete curtain rod set that can be printed and mounted. The holes are 3mm for either nails or screws, they are not threaded holes, and you only need to use one per side, not all four. On my printer it costs me roughly $4 to print it out of a $20 roll but just $1.50 for my $12 roll. I do plan to try and make an actual printable curtain, but here is the Curtain Set in application with a fleece fabric.

There are a few things I have not done. I have not made end caps and this curtain rod's diameter is not able to go through the abs holders I made before. As you can see, it isn't a particular problem but while this print is functional, I've certainly not made it pretty.
